Check in-line fuse on battery positive cable. Replace if necessary.
2.
Check fuse(s) on amplifier. Replace if necessary.
3.
Verify that Ground connection is connected to clean metal on the vehicle's chassis. Repair/replace if
necessary.
4. Verify there is 9 to 14.4 Volts present at the positive battery and remote turn-on cable.Verify quality
connections for both cables at amplifier, stereo, and battery/fuseholder. Repair/replace if necessary.
Procedure 2: Protect light is on.

If the Protect light is on, this is a sign of a possible short in the speaker connections. Check for
proper speaker connections and use a volt/ohm meter to check for possible shorts in the speaker
wiring.Too low of a speaker impedance may also cause Protect to light.

1.
Verify good RCA input connections at stereo and amplifier. Check entire length of cables for kinks,
splices, etc.Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.
